'''Rob's p16''' is a {{period|16}} [[oscillator]] that was found by [[Rob Liston]] on February 9, {{year|2020}} using [[Adam P. Goucher]]'s [[apgsearch]],<ref>{{CiteCatagolue|page=haul/b3s23/G1/477c29ce65dab871f2889810e344bece|title=Haul|accessdate=February 10, 2020}}</ref> and first noticed by a human the next day.<ref name="post89261" /> It is the smallest known period-16 oscillator in terms of both [[population]] and [[bounding box]], the first p16 to appear [[natural]]ly, the first known [[strictly volatile]] p16, and the first new [[rotor]] discovered by asymmetric soup search since the 1980s.

It also gives off weak [[spark]]s,<ref name="post89263" /> which in addition to allowing for the construction of [[non-trivial]] higher-period oscillators as seen in a [[#LCM oscillators|later section]], can be used to [[filter]] an [[LWSS]] stream resulting in a reduction to the [[pseudo-period]] p16 [[glider gun]].<ref name="post89318" /> On November 12, [[James Pascua]] constructed a p32 [[lumps of muck]] hassler using this oscillator.<ref name="post110402" /> Later James Pascua constructed a [[period-48 glider gun]] that is currently the smallest at that period, also using this oscillator.

'''34P7''' is a {{period|7}} [[oscillator]] found by [[Charity Engine]] on August 2, {{year|2022}}.<ref name="post149077" /> It is one of the useful [[period-7 sparkers]] that produces a similar [[corner dot]] [[spark]] to [[meatball]]; for an application see [[p49 R-pentomino hassler]].

Meatball and 34P7 have different profiles; while they are mostly interchangeable, there are some situations where one gets hit later on but the other doesn't. When either could be used, 34P7 has a smaller population, but meatball has a smaller bounding box.

Trivial

2025-11-22T01:31:37Z

Haycat2009:

{{Glossary}}
A period-''n'' [[oscillator]] is considered '''trivial''' if none of its cells oscillate at the full period, i.e. period ''n''. By definition, an oscillator is trivial if and only if its [[strict volatility]] is precisely 0. For a trivial oscillator, it is necessary that the period ''n'' be a [[composite number]] that is not a prime power.

Most known trivial oscillators consist of two oscillators (possibly fused together) of periods ''k'' and ''m'', which together oscillate at a greater period which is the least common multiple of ''k'' and ''m''. Trivial oscillators are not generally considered interesting, except in special cases like welds or when the rotors touch or interact.

Sometimes a trivial oscillator is useful for other purposes, such as a huge [[weld]]ed oscillator with p4 and p13 components in the [[p13-assisted period-52 glider gun]]. In this context, its triviality does not matter.

The definition of trivial has been questioned using the second example below. It has been suggested that the definition be modified as follows: An oscillator is considered trivial if no cell oscillates at the full period and none of the rotors interact with each other.<ref name="post140540" />

Phi-sparker

2025-10-01T23:49:33Z

Haycat2009:

{{Glossary}}
A '''phi-sparker''' is a sparker that emits [[phi spark]]s. These are desirable because phi sparks have many uses, for example reflecting [[glider]]s.

{{EmbedViewer
|rle = x = 15, y = 7, rule = B3/S23

This is the mechanism by which a single [[pentadecathlon]] can reflect a glider, such as in the [[p60 glider shuttle]]. However, while the pentadecathlon provides a [[T-nosed]] spark followed by a [[V spark]] in the same manner as a phi spark, not all interactions with a phi spark would work with a pentadecathlon (at least not without destroying the pentadecathlon), so the pentadecathlon is only a [[Spark#Strength of sparkers|moderate]] phi-sparker. An example of a strong phi-sparker is [[Tanner's p46]]. Like other phi-sparkers, it can reflect gliders.

In addition, it can engage in interactions that [[perturb]] a phi spark in a way that would destroy a pentadecathlon, such as in the [[p46 gliderless MWSS gun]].

Phi sparkers are occasionally used for [[domino spark]]s that are included in the phi spark.<ref name="post133923"/>

Phi-sparkers are also known for periods 15, 30 ({{LinkCatagolue|code=xp30_y5ok46y14r4y5gy0gzy26acy54r4y31121111211zy7gz4r4y0ooo0972y37227z4r4y5ooozy8878zy82s2zy8333|style=brief}}), [[Period-45 pi-heptomino hasslers|45]], 46, [[p56 phi sparker|56]], 57, 63, 64 ({{LinkCatagolue|code=xp64_ggs673eco0gzwh0rrh0hrahyjccz117csoe6301y2gg0ggx448y3sscx6m048zyc136c631y2gg0gx4a4y01033zyp4s1t552zy92560652y71zy63diiie0eiiid3|style=brief}}), 129<ref name="post153999"/>, and [[Two-glider octomino hasslers#p140|140]].{{refn|group=note|The cell corresponding with the tip of the phi spark is alive at an earlier generation of the oscillator.}} The [[three-block shifter]] emits multiple phi sparks in its evolution, and oscillators have been constructed that use it, but it is unclear if these oscillators count as phi-sparkers.

While the [[line-of-six spark]] has the same kind of symmetry as the phi spark, there are no known oscillators that produce line-of-six sparks in the way a phi-sparker does.

'''Achim's p144''' is a {{period|144}} [[oscillator]] that was found (minus all the [[block]]s) on a cylinder of width 22 by [[Achim Flammenkamp]] on July 21, {{year|1994}}. [[Dean Hickerson]] reduced it to a finite form using [[figure eight]]s the same day. The neater finite form shown here - replacing the figure eights with blocks - was found by [[David Bell]] on August 8, 1994.<ref>{{CiteHickersonOscillators|accessdate=March 14, 2020}}</ref>

It first appeared [[semi-natural]]ly on May 2, {{year|2019}}, in a [[symmetric]] [[soup]] submitted to [[Catagolue]] by [[carybe]].<ref name="post76753" />

[[Ian07]] reduced the [[glider synthesis]] of this oscillator to 13 gliders in December, {{year|2019}}.<ref name="post86541" /> This was reduced further to {{gliders|11|text=11 gliders}} with [[wwei23]]'s observations on February 28, {{year|2021}}.<ref name="post124046" /> A {{gliders|10}} synthesis was found by [[Carson Cheng]] in July {{year|2023}}.<ref name="post163869" /><ref name="j4683584327" />

See [[factory]] for a use of this oscillator.

On October 16, {{year|2021}}, [[iNoMed]] found a new "production line"<ref name="message898917201367666698" /> variant of this oscillator which can be used as a powerful active-region factory,<ref name="post136693" /><ref name="message898986268443160596" /> as well as to reduce several [[glider gun]]s with period 144n.<ref name="post136718" />

{{Rule

Determination is a rule with rulestring B2a3i/S12. It is named such due to having B2a, yet having decent tech. It has a lot of technology dealing with moon, such as rakes, puffers and lasers.
==Spaceships==
Only photons of p2 and above are possible. The 1st time it leaves bounding box, it is unstoppable as there is a line of at least 2 and it will propagate forever because of B2a and B3i.

The minimum period stream for photons is 7 due to backward sparks and the behaviour of it.

==Turing-completeness==
It is easier to prove it by consructing a computer than by W110 stripe. An 8-bit programmable computer was made with a gun, eater, reflector and duplicator, all of which Determination has. Also, this is the third rule to be proven turing-complete by computer, after Conway Life and Eppstein.

Hi, this is Haycat2009's sand box, located at levels 107-109 of the Conway Life Skyscraper. You can play with it, but no removing of my patterns or undoing my edits.

Currently I have a shovel, some sandcastle making moulds, and purple sand, although you can change it to green sand, pink sand, orange sand or even rainbow sand. What's the fun in just plain white sand? Not to mention, this is the highest sand box on earth at 487m high. Yeaaaaah!

Haycat2009:

Hi, this is Haycat2009's sand box, located at levels 107-109 of the Conway Life Skyscraper. You can play with it, but no removing of my patterns or undoing my edits.

Currently I have a shovel, some sandcastle making moulds, and purple sand, although you can change it to green sand, pink sand, orange sand or even rainbow sand. What's the fun in just plain white sand? Not to mention, this is the highest sand box on earth at 487m high. Yeaaaaah!

'''Grounded Life''' is a [[Life-like cellular automaton]] in which a [[cell]] survives from one generation to the next if it has 2 or 3 [[Neighbourhood|neighbors]], and is born if it has 3 or 5 neighbors. Under this rule, patterns tend to stabilize much more quickly than in standard [[Life]],<ref name="post5304" /> which is one of the reasons for its name.

==Patterns==
The two most common objects in Grounded Life are the [[block]] and the [[blinker]].

Some patterns work as they do in [[Life]], but many instead die off completely, such as the [[beehive]], [[boat]], [[T-tetromino]], [[pi-heptomino]], and [[stairstep hexomino]].

===Still lifes===

Because Grounded Life adds one birth transition from Life, all still lives in Grounded Life are still lives in Conway's Game of Life, but the reverse is not true. For example, the [[boat]] fails in Grounded Life.

Many small still lifes under the standard Life rules have dead cells with five alive neighbours, so the list of still lifes for the two rules are extremely different for both small and large cell counts. The smallest patterns that are still lifes in the standard Life rules but not in Grounded Life are boat (with 5 cells), beehive (with 6 cells) and [[loaf]], [[long boat]] and [[fishhook]] (with 7 cells). Thus, the smallest asymmetric still life is [[hook with tail]].

Also, any pattern using a [[house]], [[bookend]], or [[bun]] as an induction coil that is a still life under the standard rules, any extended forms of the [[ship]] or [[boat]], any still life in Life that contains a [[pre-block]] [[motif]] (that is not part of a [[hook]] or stabilised by an aircraft carrier-like formation) or a still life where a 2-cell long line stabilises a 4-cell line by induction are not still lifes in Grounded Life.

All still lifes up to 13 bits have occurred naturally, with 36 14-bit still lifes that have not been found in soup. Notably, [[barge]], [[aircraft carrier]] and [[carrier bridge carrier]] are much more common than in Life, with carrier bridge carrier being about 1,500 times as common as it is in Life, making it the most common 12-cell still life by far.

===Oscillators===

[[Natural]]ly occurring objects in this rule include oscillators of periods 2, 3, 4, 5, 8 and 26. There are also [[semi-natural]] oscillators of periods 2, 3, 4, 5, 6, 8, 10, 11, 12, 13, 16, 18, 21, 24, 26, 29, 33, 46, 82, and 142. Alien oscillators are also much more common than in similar{{which}} rules, especially 8P8 (a mirrored [[short table]]) and 8P4 (a [[pre-pulsar]] predecessor in Life).

Notably, the [[washing machine]] is much more common in this rule, even in asymmetric soups.
It is the 56th most common object in asymmetric soups and the 21st most common object in D4_x1 soups. [[Toad]]s and [[clock]]s are also significantly more common, and blinkers are more common than blocks.

===Spaceships===

Of particular note is the fact that neither the [[glider]] nor any of the [[xWSS]]es work in Grounded Life (all of them die off), giving the rule its name. No known spaceships work in both Life and Grounded Life, and it has been proven by Keith Amling that no [[c/2]], [[c/3]] or [[2c/4]] spaceships work in both Life and Grounded Life, not even sharing a single phase. The most common spaceship according to [[Catagolue]] is the [[OCA:Glider 3736|glider 3736]].

Known [[spaceship]] speeds are c/2o, c/3o, c/4o, c/5o, c/6o, 2c/5o, c/4d and c/5d.

The three smallest spaceships in {{rl|Pseudo Life}} also work.

As of late 2023, there is an ongoing search for spaceships that work in both [[Life]] and Grounded Life, as none are known yet. Such searches have had no results as of July 2025.

=== Puffers ===

There is a naturally occurring orthogonal [[glide-symmetric]] c/2 [[puffer]] with period 136, leaving three [[blinker]]s in a half-[[interchange]] formation and two [[block]]s every 68 ticks. Combining two or more puffers can give other puffers and spaceships.<ref name="post12942" /><ref name="post17286" /> The puffer engine also works in [[Pseudo Life]] (B357/S238) (where it becomes a p248 puffer). As of 2023, all known natural infinite growth relies on this puffer.
On September 10, 2021, FWKnightship posted a 24c/48 siderake emitting 2c/5 spaceships.<ref name="post135647" />

===Beehive/block reburnable fuse===
One of the most useful reactions is the following [[reburnable]] [[block fuse]], in which a beehive spark interacts with a chain of blocks, moving it further down the chain. It moves at a [[speed]] of 3c/4 orthogonal and has [[period]] 4.<ref name="post35738" />

Once the beehive reaches the end, it will reverse direction while shortening the chain, and will eventually annihilate it given enough time. This can be stopped with a [[pond]]:<ref name="post160876" />

Alternatively, a blinker following a [[pre-beehive]] also allows for a [[clean]] ignition of the block fuse, although different circuitry is needed. Similarly to the reburnable form, it moves at a speed of 3c/4 and has period 4. It also produces [[corner dot]]s.<ref name="post166070" />

==Change in frequency, stabilisation time and evolutionary sequences==
{{main|OCA:Grounded Life/List of common objects}}
From the same random starting conditions, Grounded Life usually settles into much fewer objects than in Life due to the fact that many life [[evolutionary sequence]]s are sparks in this rule. It also stabilises ten times faster than Life on average.

The [[honey farm]] sequence, which evolves into 4 [[blinker]]s in a [[traffic light]]-like formation with a [[tub]] inside, is much rarer in Grounded Life due to the fact that the only 7-cell predecessor that still works is the line of seven, which is much rarer than the other predecessors.

The traffic light sequence is considerably rarer in Grounded Life due to the [[T-tetromino]]'s disappearance, so the next most common predecessor that works is the X-[[pentomino]], which is rarer.

The [[Bakery]], [[Teardrop]], [[Butterfly]], [[R-pentomino]], [[Blonk-tie]] and [[Procrastinator]] die out. While the fully formed [[Fleet]] is stable, its predecessors die out, making it much rarer as it can only form by chance.

==Universality==
On August 3, 2023, Anivec published a {{rl|Rule 110}} unit stripe based on the aforementioned beehive/block reburnable fuse, proving the rule's [[Universal computer|Turing-completeness]]. <ref name="post164523" />

== Soup search ==
{{related|Catagolue|Tutorials/Contributing to Catagolue}}

Soup search was performed using a modified version of [[apgsearch]], yielding uncommon objects such as the c/3o spaceship (Glider 4793) as early as 2014.<ref name="post13161" />

On October 12, 2022, the {{cata|census/b35s23/C1|b35s23/C1}} census on [[Catagolue]] reached a total of one trillion objects,<ref group=c name="C1_1e12" /> making Grounded Life one of several [[Life-like rule]]s with hauls [[Catagolue#Haul verification|subject to statistical verification and peer review]] before being committed.

'''Copperhead''' is a [[c/10 orthogonal]] [[spaceship]] discovered by [[zdr]] on March 5, {{year|2016}}<ref name="post27988" /> using a new new program that later came to be known as [[zfind]], based on David Eppstein's [[gfind]] search program. It was the first spaceship of this speed to be discovered, and surprised many due to its small size and high period.

Various names were proposed on the day of the ship's discovery; for example copperhead, blockhauler, decapod, cuttlefish and blockfish. zdr settled on copperhead.<ref name="post28078" />

{{POTY|year=2016|rank=2|behind=the [[caterloopillar]]s}}

<div style="clear:left">

== Reactions ==
The ship hauls a [[block]] behind it, which makes for interesting reactions involving other ships. [[Dean Hickerson]] built a [[sawtooth]] that uses copperhead's ability to turn a [[heavyweight spaceship]] into a [[loaf]].<ref name="post28119" /> It can also eat gliders and [[middleweight spaceship]]s cleanly from behind, and [[lightweight spaceship]]s from the side of the block. Its front end can cleanly burn through [[blinker]]s, creating [[blinker fuse#c/10 orthogonal|a c/10 blinker fuse]].

=== Fireship ===
{{main|Fireship}}

[[Simon Ekström]] found what appeared to be a [[tagalong]] with a large spark on March 20, 2016.<ref name="post28956" /> Unlike most tagalongs, this tagalong actually temporarily interacts with the hauled block, and is thus not a true tagalong but a whole new spaceship, named [[fireship]] due to its unusual spark. However, blocks hauled by the tagalongs in tagalong pyramids are unaffected, and are thus true tagalongs.<ref name="post28988" />

A [[Fireship#Beehive tagalong|2c/20 tagalong for the fireship]] is also known, discovered by [[Christoph Reinthaler]] on October 11, 2018.<ref name="post64623" />

=== Cottonmouth ===
{{main|Cottonmouth}}

A true [[pushalong]] known as the [[cottonmouth]] was found by [[AforAmpere]] on March 24, 2018 for both the copperhead and the similar [[fireship]]. Because its front end matches that of the copperhead, it is infinitely [[extensible]] by stacking on itself.<ref name="post58357" />

== Occurrence ==
The first copperhead to emerge from the [[ash]] of a [[soup]] appeared on April 4, 2016 in a [[D2_+2]] [[haul]] submitted to [[Catagolue]] by [[Apple Bottom]].<ref name="post29637" /> Several more copperheads have since been found in this and other related symmetries. It was the first spaceship with a [[Standard spaceship|non-standard speed]] to appear in a soup search, and the only such spaceship until the [[c/7 orthogonal]] [[loafer]] in 2020.

== Synthesis and guns ==
The first final step for a [[glider synthesis]], starting from a large, unsynthesized still life, was proposed by [[praosylen]] on the day of discovery. An alternative synthesis utilising [[fumarole]] as a predecessor, presented by [[Tanner Jacobi]] an hour later, was much more efficient. After optimizations by [[Mark Niemiec]] and [[Chris Cain]] the total synthesis cost made 22 gliders.<ref name="post28085" /> In a different approach, [[gmc_nxtman]] reduced the copperhead's synthesis cost to 14 gliders on July 9, 2017;<ref name="post46308" /> [[2718281828]] posted a 13-glider synthesis on January 9, 2018.<ref name="post54874" />

Based on the fumarole route, [[Alexey Nigin]] constructed a period-690 copperhead [[gun]] on March 6, 2016,<ref name="post28101" /> and gmc_nxtman constructed a period-376 gun one day later.<ref name="post28176" /> On August 16, 2018, [[Goldtiger997]] posted a stable glider-to-copperhead [[converter]] based on the latter route, allowing for copperhead guns with period at least 197 to be built.<ref name="post62681" />

In {{rl|DryLife}}, an extremely similar spaceship (dubbed the '''goldenhead''') also travels at c/10 orthogonal. It differs from the normal copperhead by 2 cells in one phase. A normal copperhead at this phase will turn into a goldenhead in DryLife, and conversely this phase will return to a copperhead in normal Life.

'''Grounded Life''' is a [[Life-like cellular automaton]] in which a [[cell]] survives from one generation to the next if it has 2 or 3 [[Neighbourhood|neighbors]], and is born if it has 3 or 5 neighbors. Under this rule, patterns tend to stabilize much more quickly than in standard [[Life]],<ref name="post5304" /> which is one of the reasons for its name.

==Patterns==
The two most common objects in Grounded Life are the [[block]] and the [[blinker]].

Some patterns work as they do in [[Life]], but many instead die off completely, such as the [[beehive]], [[boat]], [[T-tetromino]], [[pi-heptomino]], and [[stairstep hexomino]].

===Still lifes===

Because Grounded Life adds one birth transition from Life, all still lives in Grounded Life are still lives in Conway's Game of Life, but the reverse is not true. For example, the [[boat]] fails in Grounded Life.

Many small still lifes under the standard Life rules have dead cells with five alive neighbours, so the list of still lifes for the two rules are extremely different for both small and large cell counts. The smallest patterns that are still lifes in the standard Life rules but not in Grounded Life are boat (with 5 cells), beehive (with 6 cells) and [[loaf]], [[long boat]] and [[fishhook]] (with 7 cells). Thus, the smallest asymmetric still life is [[hook with tail]].

Also, any pattern using a [[house]], [[bookend]], or [[bun]] as an induction coil that is a still life under the standard rules, any extended forms of the [[ship]] or [[boat]], any still life in Life that contains a [[pre-block]] [[motif]] (that is not part of a [[hook]] or stabilised by an aircraft carrier-like formation) or a still life where a 2-cell long line stabilises a 4-cell line by induction are not still lifes in Grounded Life.

All still lifes up to 13 bits have occurred naturally, with 36 14-bit still lifes that have not been found in soup. Notably, [[barge]], [[aircraft carrier]] and [[carrier bridge carrier]] are much more common than in Life, with carrier bridge carrier being about 1,500 times as common as it is in Life, making it the most common 12-cell still life by far.

===Oscillators===

[[Natural]]ly occurring objects in this rule include oscillators of periods 2, 3, 4, 5, 8 and 26. There are also [[semi-natural]] oscillators of periods 2, 3, 4, 5, 6, 8, 10, 11, 12, 13, 16, 18, 21, 24, 26, 29, 33, 46, 82, and 142. Alien oscillators are also much more common than in similar{{which}} rules, especially 8P8 (a mirrored [[short table]]) and 8P4 (a [[pre-pulsar]] predecessor in Life).

Notably, the [[washing machine]] is much more common in this rule, even in asymmetric soups.
It is the 56th most common object in asymmetric soups and the 21st most common object in D4_x1 soups. [[Toad]]s and [[clock]]s are also significantly more common, and blinkers are more common than blocks.

===Spaceships===

Of particular note is the fact that neither the [[glider]] nor any of the [[xWSS]]es work in Grounded Life (all of them die off), giving the rule its name. No known spaceships work in both Life and Grounded Life, and it has been proven by Keith Amling that no [[c/2]], [[c/3]] or [[2c/4]] spaceships work in both Life and Grounded Life, not even sharing a single phase. The most common spaceship according to [[Catagolue]] is the [[OCA:Glider 3736|glider 3736]].

Known [[spaceship]] speeds are c/2o, c/3o, c/4o, c/5o, c/6o, 2c/5o, c/4d and c/5d.

The three smallest spaceships in {{rl|Pseudo Life}} also work.

As of late 2023, there is an ongoing search for spaceships that work in both [[Life]] and Grounded Life, as none are known yet. Such searches have had no results as of July 2025.

=== Puffers ===

There is a naturally occurring orthogonal [[glide-symmetric]] c/2 [[puffer]] with period 136, leaving three [[blinker]]s in a half-[[interchange]] formation and two [[block]]s every 68 ticks. Combining two or more puffers can give other puffers and spaceships.<ref name="post12942" /><ref name="post17286" /> The puffer engine also works in [[Pseudo Life]] (B357/S238) (where it becomes a p248 puffer). As of 2023, all known natural infinite growth relies on this puffer.
On September 10, 2021, FWKnightship posted a 24c/48 siderake emitting 2c/5 spaceships.<ref name="post135647" />

===Beehive/block reburnable fuse===
One of the most useful reactions is the following [[reburnable]] [[block fuse]], in which a beehive spark interacts with a chain of blocks, moving it further down the chain. It moves at a [[speed]] of 3c/4 orthogonal and has [[period]] 4.<ref name="post35738" />

Once the beehive reaches the end, it will reverse direction while shortening the chain, and will eventually annihilate it given enough time. This can be stopped with a [[pond]]:<ref name="post160876" />

A beehive followed by <tt>n</tt> blocks turns into two vertically spaced blocks in <tt>{{frac|2n2+23n+42|3}}</tt> generations if <tt>n ≡ 2 (mod 3)</tt>, and is otherwise a [[diehard]] lasting <tt>{{frac|2n2 + 23n + {{frac|55 if n%3 {{=}}{{=}} 0 else 52|3}}|3}}</tt> generations.

These chains can interact in different ways to form logic gates.<ref name="post164488" />

Alternatively, a blinker following a [[pre-beehive]] also allows for a [[clean]] ignition of the block fuse, although different circuitry is needed. Similarly to the reburnable form, it moves at a speed of 3c/4 and has period 4. It also produces [[corner dot]]s.<ref name="post166070" />

==Change in frequency, stabilisation time and evolutionary sequences==
{{main|OCA:Grounded Life/List of common objects}}
From the same random starting conditions, Grounded Life usually settles into much fewer objects than in Life due to the fact that many life [[evolutionary sequence]]s are sparks in this rule. It also stabilises ten times faster than Life on average.

The [[honey farm]] sequence, which evolves into 4 [[blinker]]s in a [[traffic light]]-like formation with a [[tub]] inside, is much rarer in Grounded Life due to the fact that the only 7-cell predecessor that still works is the line of seven, which is much rarer than the other predecessors.

The traffic light sequence is considerably rarer in Grounded Life due to the [[T-tetromino]]'s disappearance, so the next most common predecessor that works is the X-[[pentomino]], which is rarer.

The [[Bakery]], [[Teardrop]], [[Butterfly]], [[R-pentomino]], [[Blonk-tie]] and [[Procrastinator]] die out. While the fully formed [[Fleet]] is stable, its predecessors die out, making it much rarer as it can only form by chance.

==Universality==
On August 3, 2023, Anivec published a {{rl|Rule 110}} unit stripe based on the aforementioned beehive/block reburnable fuse, proving the rule's [[Universal computer|Turing-completeness]]. <ref name="post164523" />

== Soup search ==
{{related|Catagolue|Tutorials/Contributing to Catagolue}}

Soup search was performed using a modified version of [[apgsearch]], yielding uncommon objects such as the c/3o spaceship (Glider 4793) as early as 2014.<ref name="post13161" />

On October 12, 2022, the {{cata|census/b35s23/C1|b35s23/C1}} census on [[Catagolue]] reached a total of one trillion objects,<ref group=c name="C1_1e12" /> making Grounded Life one of several [[Life-like rule]]s with hauls [[Catagolue#Haul verification|subject to statistical verification and peer review]] before being committed.

Determination is a rule with rulestring B2a3i/S12. It is named such due to having B2a, yet having decent tech. It has a lot of technology dealing with moon, such as rakes, puffers and lasers.
==Spaceships==
Only photons of p2 and above are possible. The 1st time it leaves bounding box, it is unstoppable as there is a line of at least 2 and it will propagate forever.

The minimum period stream for photons is 7 due to backward sparks and the behaviour of it.

==Turing-completeness==
It is easier to prove it by consructing a computer than by W110 stripe. An 8-bit programmable computer was made with a gun, eater, reflector and duplicator, all of which Determination has. Also, this is the third rule to be proven turing-complete by computer, after Conway Life and Eppstein.

{{Glossary}}
To '''tame a [[dirty]] reaction''' is to perturb it using other patterns such as [[glider]]s and [[catalyst]]s so as to make it [[clean]] and hopefully useful. Alternatively, the reaction may not work at all without the taming due to unwanted debris that interferes with the reaction. An example is the [[AK47 reaction]], which was independently tamed into three separate glider guns.

}}}}
{{gallery bottom}}

==Taming rules==
In addition to reactions, taming is applied to [[explosive]]/expansive rules. To '''tame a rule''' is to modify the rule's birth and survival conditions so that the resulting rule is less explosive, while keeping certain desirable properties of the original rule, such as the existence of certain patterns or reactions. Rule-taming is usually done using [[isotropic non-totalistic cellular automaton|isotropic non-totalistic rules]].

==Taming rules==
In addition to reactions, taming is applied to [[explosive]]/expansive rules. To '''tame a rule''' is to modify the rule's birth and survival conditions so that the resulting rule is less explosive, while keeping certain desirable properties of the original rule, such as the existence of certain patterns or reactions. Rule-taming is usually done using [[isotropic non-totalistic cellular automaton|isotropic non-totalistic rules]].

Tame

2025-05-18T13:50:14Z

Haycat2009: Add Examples

{{Glossary}}
To '''tame a [[dirty]] reaction''' is to perturb it using other patterns such as [[glider]]s and [[catalyst]]s so as to make it [[clean]] and hopefully useful. Alternatively, the reaction may not work at all without the taming due to unwanted debris that interferes with the reaction. An example is the [[AK47 reaction]], which was independently tamed into three separate glider guns.

Mashup rule

{{Glossary}}
{{Stub}}
A '''mashup rule''' is any rule which uses [[Multistate rule|multiple states]] to emulate multiple different rules in one [[universe]], or to emulate [[alternating rule]]s without using any alternation. Mashup rules are notably distinct from alternating rules, because in a mashup rule the different states can coexist in a single universe, whereas in an alternating rule all live cells on a given step follow the same phase of the rule. Since [[Golly]] cannot natively simulate alternating rules without the use of emulation, mashup [[ruletable]]s are the only way to simulate alternating rules that are not emulated by any [[B0]] rules.

Still life component

2025-05-15T05:08:08Z

Haycat2009:

{{Glossary}}
A '''still life component''' is any unstable [[pattern]] which can be combined with either existing still lifes or other still life components to create a proper [[still life]].

[[Induction coil]]s are a notable class of still life components, which require stabilisation from other objects (either other induction coils or self-stable patterns) which are usually detached from them, resulting in an object with multiple [[island]]s.

There are other types of components which interact differently with other objects. For example, the [[tail]] and [[nine]] are "appendage"-like structures which attach to other structures diagonally, and the [[pre-block]], [[hook]] and [[claw]] are structures which can have objects such as tails attached for mutual stabilisation.

Patterns which are stable by themselves while also accepting components, such as a [[tub]] which can be upgraded to a [[tub with tail]], are generally not considered components.

==Example==
[[Claw]] is a still life component featured in all of these still lives:

Inconstructible

Haycat2009:

{{Glossary}}
A pattern is considered '''inconstructible''' (or unsynthesizable) if it has no [[glider synthesis]], either as a matter of principle or in practice. [[Gardens of Eden]] are by definition inconstructible, but not every provably inconstructible pattern is a Garden of Eden (for example, [[unsynthesizable oscillator 1]]).

Patterns containing large amounts of [[space dust]] may be considered inconstructible in the practical sense despite not having been proven (and in fact not being) inconstructible in principle.

Pointless optimisation game

2025-05-15T04:52:17Z

Haycat2009:

{{Glossary}}
The '''Pointless Optimisation Game''' (or '''Pointless Optimization Game''' in non-British English) is a common term for a particular type of pattern optimisation. Specifically, it involves improving the [[bounding box]] area, usually of a [[glider]] [[gun]]. It often happens that small improvements in bounding box area can be made at the expense of significant increases in the population and/or complexity of the gun.

}}}}
{{gallery bottom}}

== History ==
The reason that the Pointless Optimisation Game exists as a concept is that the bounding box metric was chosen to determine the "smallest" guns in [[Dieter and Peter's gun collection]] from the 1990's. That convention continued to be followed in later collections of glider guns maintained by [[Jason Summers]], [[Chris Cain]], and [[Adam P. Goucher]]. Bounding-box-optimized guns started getting an increasing amount of attention around the year 2000, when the focus began to shift toward creating a complete collection of optimized guns for all periods between 14 and 1000. That project was completed using [[Hersrch]] in September 2003.

The slightly disparaging tone of the phrase "pointless optimisation game" is due to the fact that obsessively optimising a gun to reduce its rectangular bounding box to the lowest possible area does not necessarily produce the most generally useful gun. An [[edge shooter|edge-shooting]] gun might well be much more useful in larger patterns. For example, a gun with a small bounding octagon or narrow diagonal diameter may allow many copies to be packed more efficiently into a larger [[shotgun]] pattern like the ones found in bounding-box-optimised guns for constructible spaceships. Alternatively, a gun optimised for [[population]] could allow for easier reduction of patterns such as [[SKOP]]s and [[sawtooth|sawteeth]].

However, the bounding box is very convenient in terms of ease of calculation, for comparing different guns to determine new record-breaking entries for gun collections. So the bounding box metric has never been supplanted by any other measurement that might be technically more appropriate but would be significantly harder to calculate, such as the [[bounding diamond]], bounding octagon or [[minimum covering polyplet size]].

In the current incarnation of the glider-gun collection on [[Catagolue]], any existing gun can be replaced at any time, simply by submitting a new gun pattern that fits into a smaller bounding box area.

Finger

{{Glossary}}
A '''finger''' is a protruding cell in an [[oscillator]] or [[dying spark]], with the ability to modify a nearby active reaction. Like a [[thumb]], a finger cell appears at the edge of a reaction [[envelope]] and is the only live cell in its row or column. The finger [[spark]] remains alive for two [[tick]]s before dying, whereas a thumb cell dies after one tick. Because the key cell is kept alive for an extra tick, an alternate technical term is "held (orthogonal) bit spark". A "held diagonal bit spark" is not possible in [[Conway's Game of Life|B3/S23]] for obvious reasons.

Higher-range isotropic non-totalistic rule

2025-05-06T09:36:40Z

Haycat2009:

'''Higher-range isotropic non-totalistic''' (abbreviated as '''HRINT''') are a generalization of range-1 [[isotropic non-totalistic]] rules and of [[higher-range outer-totalistic]] rules; a rulespace with a range greater than 1 where isotropy is observed, but transitions are not necessarily totalistic.

There are a very wide variety of such rules, with limited software support.

== Classes ==

=== "Exploded" Moore neighbourhood ===
The range-1, 8-cell [[Moore neighbourhood]] can be "exploded" into other neighbourhoods consisting of four orthogonal cells of distance E and four diagonal cells of distance C.<ref name="post128801" /> Isotropic non-totalistic rules can be run using this neighbourhood using standard [[Hensel notation]].

Neighbourhoods with orthogonal cells of distance 1 and diagonal cells of distance 2, as well as with orthogonal cells of distance 3 and diagonal cells of distance 1, can be run using [[CAViewer]].

=== Range-2 cross neighbourhood ===
A proposal for a notation for this neighbourhood was created in 2017 as a result of a misunderstanding of how the range-2 von Neumann neighbourhood was to be defined.<ref name="post50386" /> A second notation for this neighbourhood was created in mid-2020,<ref name="post101003" /> however a 3-cell transition and its corresponding 5-cell transition was mistakenly omitted.<ref name="p128945">{{LinkForumThread|f=3|t=1622|p=128945|title=Re: Pattern viewer for forum threads|format=ref}}</ref>

The following notation is supported by [[CAViewer]]. Whether other programs will implement support for this rulespace currently remains unknown.
{{Isotropic non-totalistic transitions (range-2 cross)}}

=== Range-2 knight neighbourhood ===
A proposal for a notation for this neighbourhood was created in mid-2020.<ref name="post101003"/> However, the proposal duplicated one of the 4-cell transitions.<ref name="p128945"/>

The following notation is supported by CAViewer. Whether other programs will implement support for this rulespace currently remains unknown.
{{Isotropic non-totalistic transitions (range-2 knight)}}

=== 4-cell extensions ===
A notation system exists that can be used for extending existing isotropic non-totalistic rules by adding four equidistant cells, either orthogonally or diagonally aligned with the center. This can be used for notating isoptropic non-totalistic rules with the range-2 von Neumann neighbourhood, or any of the other three equivalent neighbourhoods below. It is also used for notating the range-3 cross neighbourhood by extending the range-2 cross neighbourhood.

{{EmbedViewer

3o6bo6bobo$2bo5bo3bo3bobobo3bobobo!
|viewerconfig = #C [[ NOGUI ]]
|position = center
|caption = These four neighbourhoods are effectively equivalent
}}

The extension-based notation was initially proposed on February 24, 2019 by [[AforAmpere]] and [[Milo Jacquet]] for range-2 von Neumann isotropic non-totalistic rules.<ref name="post71574" /> Prior to this, a two-letter system was proposed for said rulespace, in which two letters were used for each of the 618 possible transitions; this ultimately was not adopted.<ref name="post70180" /><ref name="post71574" />

A table for the extensions notation is as follows:
{{Isotropic non-totalistic transitions (square grid extensions)}}

For each transition, use the transition corresponding to the configuration of the center 8 cells, aligned with the canonical directions in the table above. Then take the outside 4 cells, and depending on the configurations in the table below, add that letter.

For transitions that are the same under reflections or rotations, the canonical transition is the lowest alphabetically.

'x' is used after a totalistic number. An example range-2 von Neumann rulestring is 'B3x2ic1ei5x-3kr/S0x8x'.

[[bubblegum]] has also proposed to use the 'v' character to represent outer totalistic transitions for the inner 8 cells for range-2 von Neumann rules.<ref name="post102838" />

CAViewer supports this notation for the range-2 von Neumann neighbourhood.<ref name="post113480"/>

=== 3-state, range-1 Moore neighbourhood ===
Several notations have been proposed historically. The currently accepted notation, which does not currently have software support, was published by Cyclotrons in 2023.<ref>https://conwaylife.com/forums/viewtopic.php?p=164994#p164994</ref>

== Table of isotropic non-totalistic rulespaces ==
{{split|List of rulespaces}}
The number of unique transitions for higher ranges tends to be extremely large, and the development of notations for such rules is generally infeasible. The following table documents notable examples (grids are notated with [[Schläfli symbol]]s as to simultaneously convey grid type and dimension):

[[Image:Sawtooth260_pop.png|thumb|right|A plot of population versus generation number for [[sawtooth 260]]]]
A [[sawtooth]] (plural: '''sawtooths'''{{refn|group=note|The term "sawteeth" is not in common use.}}) is a finite [[pattern]] whose population grows without bound but does not tend to infinity. In other words, it is a pattern with population that reaches new heights infinitely often, but also infinitely often drops below some fixed value. Their name comes from the fact that their plot of population versus generation number looks roughly like an ever-increasing sawtooth graph.

The [[sawtooth 1212|first sawtooth]] was constructed by [[Dean Hickerson]] in April {{year|1991}} by using a [[loaf]] [[tractor beam]] (a technique that was also used in the construction of [[sawtooth 633]]). The least infinitely repeating population of any known sawtooth is 168, attained by [[Sawtooth 168]];<ref name="post209381"/> the smallest bounding box of any known sawtooth is {{times|62|56}}, attained by a variant of [[Sawtooth 177]], Sawtooth 195.<ref name="post24384" />

==Expansion factor==
The '''expansion factor''' of a sawtooth is the limit of the ratio of successive heights (or equivalently, widths) of the "teeth" in plots of population versus generation number. Some sawtooths do not have an expansion factor under its standard definition because they have growth that is not exactly exponentially-spaced (see [[parabolic sawtooth]], [[O(sqrt(log(t)))]], [[quadratic sawtooth]] and [[sawtooth 1163]]).

OCA:Grounded Life

2025-05-03T10:19:04Z

Haycat2009:

{{Rule
|name = Grounded Life
|b = 35
|s = 23
|char = Chaotic
|ruleinteger = 6184
|reversal = B0123478/S0124678
}}
'''Grounded Life''' is a [[Life-like cellular automaton]] in which a [[cell]] survives from one generation to the next if it has 2 or 3 [[Neighbourhood|neighbors]], and is born if it has 3 or 5 neighbors. Under this rule, patterns tend to stabilize much more quickly than in standard [[Life]],<ref name="post5304" /> which is one of the reasons for its name.

==Patterns==
The two most common objects in Grounded Life are the [[block]] and the [[blinker]].

Some patterns work as they do in [[Life]], but many instead die off completely, such as the [[beehive]], [[boat]], [[T-tetromino]], [[pi-heptomino]], and [[stairstep hexomino]].

===Still lifes===

Because Grounded Life adds one birth transition from Life, all still lives in Grounded Life are still lives in Conway's Game of Life, but the reverse is not true. For example, the [[boat]] fails in Grounded Life.

Many small still lifes under the standard Life rules have dead cells with five alive neighbours, so the list of still lifes for the two rules are extremely different for both small and large cell counts. The smallest patterns that are still lifes in the standard Life rules but not in Grounded Life are boat (with 5 cells), beehive (with 6 cells) and [[loaf]], [[long boat]] and [[fishhook]] (with 7 cells). Thus, the smallest asymmetric still life is [[hook with tail]].

Also, any pattern using a [[house]], [[bookend]], or [[bun]] as an induction coil that is a still life under the standard rules, any extended forms of the [[ship]] or [[boat]], any still life in Life that contains a [[pre-block]] [[motif]] (that is not part of a [[hook]] or stabilised by an aircraft carrier-like formation) or a still life where a 2-cell long line stabilises a 4-cell line by induction are not still lifes in Grounded Life.

All still lifes up to 13 bits have occurred naturally, with 36 14-bit still lifes that have not been found in soup. Notably, [[barge]], [[aircraft carrier]] and [[carrier bridge carrier]] are much more common than in Life, with carrier bridge carrier being about 1,500 times as common as it is in Life, making it the most common 12-cell still life by far.

===Oscillators===

[[Natural]]ly occurring objects in this rule include oscillators of periods 2, 3, 4, 5, 8 and 26. There are also [[semi-natural]] oscillators of periods 2, 3, 4, 5, 6, 8, 10, 11, 12, 13, 16, 18, 21, 24, 26, 29, 33, 46, 82, and 142. Alien oscillators are also much more common than in similar{{which}} rules, especially 8P8 (a mirrored [[short table]]) and 8P4 (a [[pre-pulsar]] predecessor in Life).

Notably, the [[washing machine]] is much more common in this rule, even in asymmetric soups.
It is the 56th most common object in asymmetric soups and the 21st most common object in D4_x1 soups. [[Toad]]s and [[clock]]s are also significantly more common, and blinkers are more common than blocks.

===Spaceships===

Of particular note is the fact that neither the [[glider]] nor any of the [[xWSS]]es work in Grounded Life (all of them die off), giving the rule its name. No known spaceships work in both Life and Grounded Life, and it has been proven by Keith Amling that no [[c/2]], [[c/3]] or [[2c/4]] spaceships work in both Life and Grounded Life, not even sharing a single phase. The most common spaceship according to [[Catagolue]] is the [[OCA:Glider 3736|glider 3736]].

Known [[spaceship]] speeds are c/2o, c/3o, c/4o, c/5o, c/6o, 2c/5o, c/4d and c/5d.

The three smallest spaceships in {{rl|Pseudo Life}} also work.

In particular, many [[tagalong]]s for 90P4H1V1 and 18P2H1V0 are known. This is due to their easily-connectable-to spark.

As of late 2023, there is an ongoing search for spaceships that work in both [[Life]] and Grounded Life, as none are known yet. Such searches have had no results as of March 2024.

=== Puffers ===

There is a naturally occurring orthogonal [[glide-symmetric]] c/2 [[puffer]] with period 136, leaving three [[blinker]]s in a half-[[interchange]] formation and two [[block]]s every 68 ticks. Combining two or more puffers can give other puffers and spaceships.<ref name="post12942" /><ref name="post17286" /> The puffer engine also works in [[Pseudo Life]] (B357/S238) (where it becomes a p248 puffer). As of 2023, all known natural infinite growth relies on this puffer.
On September 10, 2021, FWKnightship posted a 24c/48 siderake emitting 2c/5 spaceships.<ref name="post135647" />

===Beehive/block reburnable fuse===
One of the most useful reactions is the following [[reburnable]] [[block fuse]], in which a beehive spark interacts with a chain of blocks, moving it further down the chain. It moves at a [[speed]] of 3c/4 orthogonal and has [[period]] 4.<ref name="post35738" />

Once the beehive reaches the end, it will reverse direction while shortening the chain, and will eventually annihilate it given enough time. This can be stopped with a [[pond]]:<ref name="post160876" />

A beehive followed by <tt>n</tt> blocks turns into two vertically spaced blocks in <tt>{{frac|2n2+23n+42|3}}</tt> generations if <tt>n ≡ 2 (mod 3)</tt>, and is otherwise a [[diehard]] lasting <tt>{{frac|2n2 + 23n + {{frac|55 if n%3 {{=}}{{=}} 0 else 52|3}}|3}}</tt> generations.

These chains can interact in different ways to form logic gates.<ref name="post164488" />

Alternatively, a blinker following a [[pre-beehive]] also allows for a [[clean]] ignition of the block fuse, although different circuitry is needed. Similarly to the reburnable form, it moves at a speed of 3c/4 and has period 4. It also produces [[corner dot]]s.<ref name="post166070" />

==Change in frequency, stabilisation time and evolutionary sequences==
{{main|OCA:Grounded Life/List of common objects}}
From the same random starting conditions, Grounded Life usually settles into much fewer objects than in Life due to the fact that many life [[evolutionary sequence]]s are sparks in this rule. It also stabilises ten times faster than Life on average.

The [[honey farm]] sequence, which evolves into 4 [[blinker]]s in a [[traffic light]]-like formation with a [[tub]] inside, is much rarer in Grounded Life due to the fact that the only 7-cell predecessor that still works is the line of seven, which is much rarer than the other predecessors.

The traffic light sequence is considerably rarer in Grounded Life due to the [[T-tetromino]]'s disappearance, so the next most common predecessor that works is the X-[[pentomino]], which is rarer.

The [[Bakery]], [[Teardrop]], [[Butterfly]], [[R-pentomino]], [[Blonk-tie]] and [[Procrastinator]] die out. While the fully formed [[Fleet]] is stable, its predecessors die out, making it much rarer as it can only form by chance.

==Universality==
On August 3, 2023, AlbertArmStain published a {{rl|Rule 110}} unit stripe based on the aforementioned beehive/block reburnable fuse, proving the rule's [[Universal computer|Turing-completeness]]. <ref name="post164523" />

== Soup search ==
{{related|Catagolue|Tutorials/Contributing to Catagolue}}

Soup search was performed using a modified version of [[apgsearch]], yielding uncommon objects such as the c/3o spaceship (Glider 4793) as early as 2014.<ref name="post13161" />

On October 12, 2022, the {{cata|census/b35s23/C1|b35s23/C1}} census on [[Catagolue]] reached a total of one trillion objects,<ref group=c name="C1_1e12" /> making Grounded Life one of several [[Life-like rule]]s with hauls [[Catagolue#Haul verification|subject to statistical verification and peer review]] before being committed.

The b35s23/C1 census accumulated 375 million objects in April 2015,<ref group=c>[https://web.archive.org/web/20150422135228/http://catagolue.appspot.com/census/b35s23/C1 /census/b35s23/C1] (archived copy as of 2015-04-22)</ref>

'''Grounded Life''' is a [[Life-like cellular automaton]] in which a [[cell]] survives from one generation to the next if it has 2 or 3 [[Neighbourhood|neighbors]], and is born if it has 3 or 5 neighbors. Under this rule, patterns tend to stabilize much more quickly than in standard [[Life]],<ref name="post5304" /> which is one of the reasons for its name.

==Patterns==
The two most common objects in Grounded Life are the [[block]] and the [[blinker]].

Some patterns work as they do in [[Life]], but many instead die off completely, such as the [[beehive]], [[boat]], [[T-tetromino]], [[pi-heptomino]], and [[stairstep hexomino]].

===Still lifes===

Because Grounded Life adds one birth transition from Life, all still lives in Grounded Life are still lives in Conway's Game of Life, but the reverse is not true. For example, the [[boat]] fails in Grounded Life.

Many small still lifes under the standard Life rules have dead cells with five alive neighbours, so the list of still lifes for the two rules are extremely different for both small and large cell counts. The smallest patterns that are still lifes in the standard Life rules but not in Grounded Life are boat (with 5 cells), beehive (with 6 cells) and [[loaf]], [[long boat]] and [[fishhook]] (with 7 cells). Thus, the smallest asymmetric still life is [[hook with tail]].

Also, any pattern using a [[house]], [[bookend]], or [[bun]] as an induction coil that is a still life under the standard rules, any extended forms of the [[ship]] or [[boat]], any still life in Life that contains a [[pre-block]] [[motif]] (that is not part of a [[hook]] or stabilised by an aircraft carrier-like formation) or a still life where a 2-cell long line stabilises a 4-cell line by induction are not still lifes in Grounded Life.

All still lifes up to 13 bits have occurred naturally, with 36 14-bit still lifes that have not been found in soup. Notably, [[barge]], [[aircraft carrier]] and [[carrier bridge carrier]] are much more common than in Life, with carrier bridge carrier being about 1,500 times as common as it is in Life, making it the most common 12-cell still life by far.

===Oscillators===

[[Natural]]ly occurring objects in this rule include oscillators of periods 2, 3, 4, 5, 8 and 26. There are also [[semi-natural]] oscillators of periods 2, 3, 4, 5, 6, 8, 10, 11, 12, 13, 16, 18, 21, 24, 26, 29, 33, 46, 82, and 142. Alien oscillators are also much more common than in similar{{which}} rules, especially 8P8 (a mirrored [[short table]]) and 8P4 (a [[pre-pulsar]] predecessor in Life).

Notably, the [[washing machine]] is much more common in this rule, even in asymmetric soups.
It is the 56th most common object in asymmetric soups and the 21st most common object in D4_x1 soups. [[Toad]]s and [[clock]]s are also significantly more common, and blinkers are more common than blocks.

===Spaceships===

Of particular note is the fact that neither the [[glider]] nor any of the [[xWSS]]es work in Grounded Life (all of them die off), giving the rule its name. No known spaceships work in both Life and Grounded Life, and it has been proven by Keith Amling that no [[c/2]], [[c/3]] or [[2c/4]] spaceships work in both Life and Grounded Life. The most common spaceship according to [[Catagolue]] is the [[OCA:Glider 3736|glider 3736]].

Known [[spaceship]] speeds are c/2o, c/3o, c/4o, c/5o, c/6o, 2c/5o, c/4d and c/5d.

The three smallest spaceships in {{rl|Pseudo Life}} also work.

In particular, many [[tagalong]]s for 90P4H1V1 and 18P2H1V0 are known. This is due to their easily-connectable-to spark.

As of late 2023, there is an ongoing search for spaceships that work in both [[Life]] and Grounded Life, as none are known yet. Such searches have had no results as of March 2024.

=== Puffers ===

There is a naturally occurring orthogonal [[glide-symmetric]] c/2 [[puffer]] with period 136, leaving three [[blinker]]s in a half-[[interchange]] formation and two [[block]]s every 68 ticks. Combining two or more puffers can give other puffers and spaceships.<ref name="post12942" /><ref name="post17286" /> The puffer engine also works in [[Pseudo Life]] (B357/S238) (where it becomes a p248 puffer). As of 2023, all known natural infinite growth relies on this puffer.
On September 10, 2021, FWKnightship posted a 24c/48 siderake emitting 2c/5 spaceships.<ref name="post135647" />

===Beehive/block reburnable fuse===
One of the most useful reactions is the following [[reburnable]] [[block fuse]], in which a beehive spark interacts with a chain of blocks, moving it further down the chain. It moves at a [[speed]] of 3c/4 orthogonal and has [[period]] 4.<ref name="post35738" />

Once the beehive reaches the end, it will reverse direction while shortening the chain, and will eventually annihilate it given enough time. This can be stopped with a [[pond]]:<ref name="post160876" />

A beehive followed by <tt>n</tt> blocks turns into two vertically spaced blocks in <tt>{{frac|2n2+23n+42|3}}</tt> generations if <tt>n ≡ 2 (mod 3)</tt>, and is otherwise a [[diehard]] lasting <tt>{{frac|2n2 + 23n + {{frac|55 if n%3 {{=}}{{=}} 0 else 52|3}}|3}}</tt> generations.

These chains can interact in different ways to form logic gates.<ref name="post164488" />

Alternatively, a blinker following a [[pre-beehive]] also allows for a [[clean]] ignition of the block fuse, although different circuitry is needed. Similarly to the reburnable form, it moves at a speed of 3c/4 and has period 4. It also produces [[corner dot]]s.<ref name="post166070" />

==Change in frequency, stabilisation time and evolutionary sequences==
{{main|OCA:Grounded Life/List of common objects}}
From the same random starting conditions, Grounded Life usually settles into much fewer objects than in Life due to the fact that many life [[evolutionary sequence]]s are sparks in this rule. It also stabilises ten times faster than Life on average.

The [[honey farm]] sequence, which evolves into 4 [[blinker]]s in a [[traffic light]]-like formation with a [[tub]] inside, is much rarer in Grounded Life due to the fact that the only 7-cell predecessor that still works is the line of seven, which is much rarer than the other predecessors.

The traffic light sequence is considerably rarer in Grounded Life due to the [[T-tetromino]]'s disappearance, so the next most common predecessor that works is the X-[[pentomino]], which is rarer.

The [[Bakery]], [[Teardrop]], [[Butterfly]], [[R-pentomino]], [[Blonk-tie]] and [[Procrastinator]] die out. While the fully formed [[Fleet]] is stable, its predecessors die out, making it much rarer as it can only form by chance.

==Universality==
On August 3, 2023, AlbertArmStain published a {{rl|Rule 110}} unit stripe based on the aforementioned beehive/block reburnable fuse, proving the rule's [[Universal computer|Turing-completeness]]. <ref name="post164523" />

== Soup search ==
{{related|Catagolue|Tutorials/Contributing to Catagolue}}

Soup search was performed using a modified version of [[apgsearch]], yielding uncommon objects such as the c/3o spaceship (Glider 4793) as early as 2014.<ref name="post13161" />

On October 12, 2022, the {{cata|census/b35s23/C1|b35s23/C1}} census on [[Catagolue]] reached a total of one trillion objects,<ref group=c name="C1_1e12" /> making Grounded Life one of several [[Life-like rule]]s with hauls [[Catagolue#Haul verification|subject to statistical verification and peer review]] before being committed.

'''Grounded Life''' is a [[Life-like cellular automaton]] in which a [[cell]] survives from one generation to the next if it has 2 or 3 [[Neighbourhood|neighbors]], and is born if it has 3 or 5 neighbors. Under this rule, patterns tend to stabilize much more quickly than in standard [[Life]],<ref name="post5304" /> which is one of the reasons for its name.

==Patterns==
The two most common objects in Grounded Life are the [[block]] and the [[blinker]].

Some patterns work as they do in [[Life]], but many instead die off completely, such as the [[beehive]], [[boat]], [[T-tetromino]], [[pi-heptomino]], and [[stairstep hexomino]].

===Still lifes===

Because Grounded Life adds one birth transition from Life, all still lives in Grounded Life are still lives in Conway's Game of Life, but the reverse is not true. For example, the [[boat]] fails in Grounded Life.

Many small still lifes under the standard Life rules have dead cells with five alive neighbours, so the list of still lifes for the two rules are extremely different for both small and large cell counts. The smallest patterns that are still lifes in the standard Life rules but not in Grounded Life are boat (with 5 cells), beehive (with 6 cells) and [[loaf]], [[long boat]] and [[fishhook]] (with 7 cells). Thus, the smallest asymmetric still life is [[hook with tail]].

Also, any pattern using a [[house]], [[bookend]], or [[bun]] as an induction coil that is a still life under the standard rules, any extended forms of the [[ship]] or [[boat]], any still life in Life that contains a [[pre-block]] [[motif]] (that is not part of a [[hook]] or stabilised by an aircraft carrier-like formation) or a still life where a 2-cell long line stabilises a 4-cell line by induction are not still lifes in Grounded Life.

All still lifes up to 13 bits have occurred naturally, with 36 14-bit still lifes that have not been found in soup. Notably, [[barge]], [[aircraft carrier]] and [[carrier bridge carrier]] are much more common than in Life, with carrier bridge carrier being about 1,500 times as common as it is in Life, making it the most common 12-cell still life by far.

===Oscillators===

[[Natural]]ly occurring objects in this rule include oscillators of periods 2, 3, 4, 5, 8 and 26. There are also [[semi-natural]] oscillators of periods 2, 3, 4, 5, 6, 8, 10, 11, 12, 13, 16, 18, 21, 24, 26, 29, 33, 46, 82, and 142. Alien oscillators are also much more common than in similar{{which}} rules, especially 8P8 (a mirrored [[short table]]) and 8P4 (a [[pre-pulsar]] predecessor in Life).

Notably, the [[washing machine]] is much more common in this rule, even in asymmetric soups.
It is the 56th most common object in asymmetric soups and the 21st most common object in D4_x1 soups. [[Toad]]s and [[clock]]s are also significantly more common, and blinkers are more common than blocks.

===Spaceships===

Of particular note is the fact that neither the [[glider]] nor any of the [[xWSS]]es work in Grounded Life (all of them die off), giving the rule its name. No known spaceships work in both Life and Grounded Life, and it has been proven by Keith Amling that no [[c/2]], [[c/3]] or [[2c/5]] spaceships work in both Life and Grounded Life. The most common spaceship according to [[Catagolue]] is the [[OCA:Glider 3736|glider 3736]].

Known [[spaceship]] speeds are c/2o, c/3o, c/4o, c/5o, c/6o, 2c/5o, c/4d and c/5d.

The three smallest spaceships in {{rl|Pseudo Life}} also work.

As of late 2023, there is an ongoing search for spaceships that work in both [[Life]] and Grounded Life, as none are known yet. Such searches have had no results as of March 2024.

=== Puffers ===

There is a naturally occurring orthogonal [[glide-symmetric]] c/2 [[puffer]] with period 136, leaving three [[blinker]]s in a half-[[interchange]] formation and two [[block]]s every 68 ticks. Combining two or more puffers can give other puffers and spaceships.<ref name="post12942" /><ref name="post17286" /> The puffer engine also works in [[Pseudo Life]] (B357/S238) (where it becomes a p248 puffer). As of 2023, all known natural infinite growth relies on this puffer.
On September 10, 2021, FWKnightship posted a 24c/48 siderake emitting 2c/5 spaceships.<ref name="post135647" />

===Beehive/block reburnable fuse===
One of the most useful reactions is the following [[reburnable]] [[block fuse]], in which a beehive spark interacts with a chain of blocks, moving it further down the chain. It moves at a [[speed]] of 3c/4 orthogonal and has [[period]] 4.<ref name="post35738" />

Once the beehive reaches the end, it will reverse direction while shortening the chain, and will eventually annihilate it given enough time. This can be stopped with a [[pond]]:<ref name="post160876" />

These chains can interact in different ways to form logic gates.<ref name="post164488" />

Alternatively, a blinker following a [[pre-beehive]] also allows for a [[clean]] ignition of the block fuse, although different circuitry is needed. Similarly to the reburnable form, it moves at a speed of 3c/4 and has period 4. It also produces [[corner dot]]s.<ref name="post166070" />

==Change in frequency, stabilisation time and evolutionary sequences==
{{main|OCA:Grounded Life/List of common objects}}
From the same random starting conditions, Grounded Life usually settles into much fewer objects than in Life due to the fact that many life [[evolutionary sequence]]s are sparks in this rule. It also stabilises ten times faster than Life on average.

The [[honey farm]] sequence, which evolves into 4 [[blinker]]s in a [[traffic light]]-like formation with a [[tub]] inside, is much rarer in Grounded Life due to the fact that the only 7-cell predecessor that still works is the line of seven, which is much rarer than the other predecessors.

The traffic light sequence is considerably rarer in Grounded Life due to the [[T-tetromino]]'s disappearance, so the next most common predecessor that works is the X-[[pentomino]], which is rarer.

The [[Bakery]], [[Teardrop]], [[Butterfly]], [[R-pentomino]], [[Blonk-tie]] and [[Procrastinator]] die out. While the fully formed [[Fleet]] is stable, its predecessors die out, making it much rarer as it can only form by chance.

==Universality==
On August 3, 2023, AlbertArmStain published a {{rl|Rule 110}} unit stripe based on the aforementioned beehive/block reburnable fuse, proving the rule's [[Universal computer|Turing-completeness]]. <ref name="post164523" />

== Soup search ==
{{related|Catagolue|Tutorials/Contributing to Catagolue}}

Soup search was performed using a modified version of [[apgsearch]], yielding uncommon objects such as the c/3o spaceship (Glider 4793) as early as 2014.<ref name="post13161" />

On October 12, 2022, the {{cata|census/b35s23/C1|b35s23/C1}} census on [[Catagolue]] reached a total of one trillion objects,<ref group=c name="C1_1e12" /> making Grounded Life one of several [[Life-like rule]]s with hauls [[Catagolue#Haul verification|subject to statistical verification and peer review]] before being committed.

'''Grounded Life''' is a [[Life-like cellular automaton]] in which a [[cell]] survives from one generation to the next if it has 2 or 3 [[Neighbourhood|neighbors]], and is born if it has 3 or 5 neighbors. Under this rule, patterns tend to stabilize much more quickly than in standard [[Life]],<ref name="post5304" /> which is one of the reasons for its name.

==Patterns==
The two most common objects in Grounded Life are the [[block]] and the [[blinker]].

Some patterns work as they do in [[Life]], but many instead die off completely, such as the [[beehive]], [[boat]], [[T-tetromino]], [[pi-heptomino]], and [[stairstep hexomino]].

===Still lifes===

Because Grounded Life adds one birth transition from Life, all still lives in Grounded Life are still lives in Conway's Game of Life, but the reverse is not true. For example, the [[boat]] fails in Grounded Life.

Many small still lifes under the standard Life rules have dead cells with five alive neighbours, so the list of still lifes for the two rules are extremely different for both small and large cell counts. The smallest patterns that are still lifes in the standard Life rules but not in Grounded Life are boat (with 5 cells), beehive (with 6 cells) and [[loaf]], [[long boat]] and [[fishhook]] (with 7 cells). Thus, the smallest asymmetric still life is [[hook with tail]].

Also, any pattern using a [[house]], [[bookend]], or [[bun]] as an induction coil that is a still life under the standard rules, any extended forms of the [[ship]] or [[boat]], any still life in Life that contains a [[pre-block]] [[motif]] (that is not part of a [[hook]] or stabilised by an aircraft carrier-like formation) or a still life where a 2-cell long line stabilises a 4-cell line by induction are not still lifes in Grounded Life.

All still lifes up to 13 bits have occurred naturally, with 36 14-bit still lifes that have not been found in soup. Notably, [[barge]], [[aircraft carrier]] and [[carrier bridge carrier]] are much more common than in Life, with carrier bridge carrier being about 1,500 times as common as it is in Life, making it the most common 12-cell still life by far.

===Oscillators===

[[Natural]]ly occurring objects in this rule include oscillators of periods 2, 3, 4, 5, 8 and 26. There are also [[semi-natural]] oscillators of periods 2, 3, 4, 5, 6, 8, 10, 11, 12, 13, 16, 18, 21, 24, 26, 29, 33, 46, 82, and 142. Alien oscillators are also much more common than in similar{{which}} rules, especially 8P8 (a mirrored [[short table]]) and 8P4 (a [[pre-pulsar]] predecessor in Life).

Notably, the [[washing machine]] is much more common in this rule, even in asymmetric soups.
It is the 56th most common object in asymmetric soups and the 21st most common object in D4_x1 soups. [[Toad]]s and [[clock]]s are also significantly more common, and blinkers are more common than blocks.

{{LinkCatagolue|xp2_62bd46|rule=b35s23|patternname=12P2|style=raw}} and [[Washing machine]] (rare examples of [[billiard table]]s in Grounded Life. Note that washing machine still works in Life, but is notably more common in this rule and is thus mentioned.), 
{{LinkCatagolue|xp3_2ir0qcez03|rule=b35s23|patternname=14P3|style=raw}} (a natural oscillator resembling the [[caterer]]), 
{{LinkCatagolue|xp4_hrh|rule=b35s23|patternname=8P4|style=raw}} (a [[pre-pulsar]] predecessor in rules without B5e as it is dependant on that transition. It resembles 8P8.), 
{{LinkCatagolue|xp4_ffff|rule=b35s23|patternname=12P4|style=raw}} (dependent on the B5a transition; the pattern dies in Life due to the lack of it. Also most common in [[one-cell-thick pattern]]s and C4_4, instead of its native symmetry, D8_4. ),

{{LinkCatagolue|xp10_y2gr3zcc04671dc0oo80cczy3gn31zy311|rule=b35s23|patternname=36P10|style=raw}} (p10 flipper with mod 5), 
{{LinkCatagolue|xp6_7ey0e7z01u44u1z0872278ze7y07e|rule=b35s23|patternname=46P6|style=raw}} (Four [[rock]] toads hassling unknown active region, also a strong [[emulator|middleweight]] [[spark]]er), 
{{LinkCatagolue|xp8_2d7777d2|rule=b35s23|patternname=14P8|style=raw}} (extensible, although only in discrete lengths or with proper [[induction coil]]s. Also dependent on the B5a transition; the pattern dies in Life due to the lack of it), 
{{LinkCatagolue|xp8_rar|rule=b35s23|patternname=8P8|style=raw}} (a mirrored [[short table]]), 
{{LinkCatagolue|xp33_131oowoo131zxoowooz464y2464|rule=b35s23|patternname=32P33|style=raw}} (four [[block]]s hassling four [[T-tetromino]]s),

{{LinkCatagolue|xp26_ggw77toz1bee|rule=b35s23|patternname=18P26|style=raw}} (the highest-period oscillator to have appeared naturally), 
{{LinkCatagolue|xp26_cccy177zwggy1ooozw33|rule=b35s23|patternname=24P26|style=raw}} (an oscillator composed of interacting beehive sparks; appears in 1 in 1250 C4_4 soups), 
{{LinkCatagolue|xp46_caey5ea4w756z0caczydckcz0o8ow8ksy5skczw11|rule=b35s23|patternname=48P46|style=raw}} (a [[shuttle]] of [[loaf]] and [[beehive]] sparks),

===Spaceships===

Of particular note is the fact that neither the [[glider]] nor any of the [[xWSS]]es work in Grounded Life (all of them die off), giving the rule its name. No known spaceships work in both Life and Grounded Life, and it has been proven by Keith Amling that no [[c/2]], [[c/3]] or [[2c/4]] spaceships work in both Life and Grounded Life. The most common spaceship according to [[Catagolue]] is the [[OCA:Glider 3736|glider 3736]].

Known [[spaceship]] speeds are c/2o, c/3o, c/4o, c/5o, c/6o, 2c/5o, c/4d and c/5d.

The three smallest spaceships in {{rl|Pseudo Life}} also work.

As of late 2023, there is an ongoing search for spaceships that work in both [[Life]] and Grounded Life, as none are known yet. Such searches have had no results as of March 2024.

=== Puffers ===

There is a naturally occurring orthogonal [[glide-symmetric]] c/2 [[puffer]] with period 136, leaving three [[blinker]]s in a half-[[interchange]] formation and two [[block]]s every 68 ticks. Combining two or more puffers can give other puffers and spaceships.<ref name="post12942" /><ref name="post17286" /> The puffer engine also works in [[Pseudo Life]] (B357/S238) (where it becomes a p248 puffer). As of 2023, all known natural infinite growth relies on this puffer.
On September 10, 2021, FWKnightship posted a 24c/48 siderake emitting 2c/5 spaceships.<ref name="post135647" />

===Beehive/block reburnable fuse===
One of the most useful reactions is the following [[reburnable]] [[block fuse]], in which a beehive spark interacts with a chain of blocks, moving it further down the chain. It moves at a [[speed]] of 3c/4 orthogonal and has [[period]] 4.<ref name="post35738" />

Once the beehive reaches the end, it will reverse direction while shortening the chain, and will eventually annihilate it given enough time. This can be stopped with a [[pond]]:<ref name="post160876" />

A beehive followed by <tt>n</tt> blocks turns into two vertically spaced blocks in <tt>{{frac|2n2+23n+42|3}}</tt> generations if <tt>n ≡ 2 (mod 3)</tt>, and is otherwise a [[diehard]] lasting <tt>{{frac|2n2 + 23n + {{frac|55 if n%3 {{=}}{{=}} 0 else 52|3}}|3}}</tt> generations.

These chains can interact in different ways to form logic gates.<ref name="post164488" />

Alternatively, a blinker following a [[pre-beehive]] also allows for a [[clean]] ignition of the block fuse, although different circuitry is needed. Similarly to the reburnable form, it moves at a speed of 3c/4 and has period 4. It also produces [[corner dot]]s.<ref name="post166070" />

==Change in frequency, stabilisation time and evolutionary sequences==
{{main|OCA:Grounded Life/List of common objects}}
From the same random starting conditions, Grounded Life usually settles into much fewer objects than in Life due to the fact that many life [[evolutionary sequence]]s are sparks in this rule. It also stabilises ten times faster than Life on average.

The [[honey farm]] sequence, which evolves into 4 [[blinker]]s in a [[traffic light]]-like formation with a [[tub]] inside, is much rarer in Grounded Life due to the fact that the only 7-cell predecessor that still works is the line of seven, which is much rarer than the other predecessors.

The traffic light sequence is considerably rarer in Grounded Life due to the [[T-tetromino]]'s disappearance, so the next most common predecessor that works is the X-[[pentomino]], which is rarer.

The [[Bakery]], [[Teardrop]], [[Butterfly]], [[R-pentomino]], [[Blonk-tie]] and [[Procrastinator]] die out. While the fully formed [[Fleet]] is stable, its predecessors die out, making it much rarer as it can only form by chance.

==Universality==
On August 3, 2023, AlbertArmStain published a {{rl|Rule 110}} unit stripe based on the aforementioned beehive/block reburnable fuse, proving the rule's [[Universal computer|Turing-completeness]]. <ref name="post164523" />

== Soup search ==
{{related|Catagolue|Tutorials/Contributing to Catagolue}}

Soup search was performed using a modified version of [[apgsearch]], yielding uncommon objects such as the c/3o spaceship (Glider 4793) as early as 2014.<ref name="post13161" />

On October 12, 2022, the {{cata|census/b35s23/C1|b35s23/C1}} census on [[Catagolue]] reached a total of one trillion objects,<ref group=c name="C1_1e12" /> making Grounded Life one of several [[Life-like rule]]s with hauls [[Catagolue#Haul verification|subject to statistical verification and peer review]] before being committed.

The b35s23/C1 census accumulated 375 million objects in April 2015,<ref group=c>[https://web.archive.org/web/20150422135228/http://catagolue.appspot.com/census/b35s23/C1 /census/b35s23/C1] (archived copy as of 2015-04-22)</ref>

... that all still lifes up to [[:Category:Strict still lifes with 22 cells|22 bits]] have a known [[glider synthesis]], but that there is [[Unique father problem#Reductions|a 154-cell still life]] that cannot be synthesised, so there is a [[population]] threshold between these at which not all still lifes can be constructed?

__NOEDITSECTION__

Hi! I am Haycat Durnak, but please refer to me as Haycat. Welcome to my profile! Talk to me if you have any concerns regarding [[OCA:Grounded Life|B35/S23]], B38/S234c, [[User:C28/Zlife|B3/S234z]], [[User:Haycat2009/OCA:Integration|B3/S2-i34cw]], B3/S235e, [[User:Haycat2009/OCA:Determination|B2a3i/S12]] or [[User:H. H. P. M. P. Cole/The R3 Cross Rulespace|R3 cross rules]].

Working on sussy plans. If you are reckless, you can go in - but these plans might ruin you. In real life.

I also own the 103-109th floor of the Conway Life Skyscraper, and have built a sand box there at levels 107-109. Admission is free and public - but no vandalising please.

Trying to turn this wiki from a war zone to a real wiki. I am an extremely prolific editor and wikiDragon (Seemingly the third, after one other user and Entity Valkyrie), but sometimes I make honest mistakes (Dvgrn once told me to slow down, so instead of the past 100+++ edits per day, now I make 20-50)

Fun fact: I have gone on no less than two journeys into the CA world. Once to the Sands Of Grounded Life, and once to Factorioland.

Important note: Apparently there are some misconceptions surrounding my username. So I will make it clear: The 2009 is a random number selected by a random number generator for 4 digits. '''IT IS NEITHER A YEAR, NOR A BIRTH DATE.'''
